Last month, Amazon also announced the Amazon Storage Gateway. The product is a vSphere virtual appliance that allows you to snapshot your storage volumes (SAN, NAS, or direct-attach) to Amazon’s S3 cloud. The cool thing is that is presents itself back as a block-level iSCSI volume to the three supported platforms: Windows 7, Windows 2008, or Red Hat Enterprise Linux 5. I missed the webinar on it as well, but uncovered a hands-on eval of the product that found some rough edges, such as the need for scripting to get full functionality, static volume sizes and a strange dependency on DHCP.
